Which equation represents an exponential function with an initial value of 500? f(x) = 100(5)x f(x) = 100(x)5 f(x) = 500(2)x f(x) = 500(x)2

So we want to know which equation represents an exponential function with an initial value of f(0)=500. We can find that out if we simply input 0 instead of x. So first function: f(0)=100^5*0=0, second functon: f(0)=100*0^5=0, third function: f(0)=500*2^0=500 and fourth function f(0)=500*0^2=0. So we can see that the third function is the correct answer.
